8:00 - 10:00 a.m.
Concepts and Advancements in Shock Testing
Chair: Nick Clinkinbeard, Rockwell Collins
Shock testing is critical to the success of many industry, military, and space programs. The diverse approaches taken to reproduce such events in a laboratory or test site setting make this a challenging and continually-changing field. Advances in test methodologies, data acquisition, and post-test data analysis continually improve the quality and consistency of shock simulation, while presenting new and often unforeseen challenges.

  • Exploring the Limits of Mid-Field Pyroshock on Electrodynamic Shakers -- Benjamin Shank, Thermotron Industries
  • Testing Compliance of High-G Shock Accelerometers to MIL-STD-810G, Change Notice 1 -- Vesta Bateman, Mechanical Shock Consulting
  • Synthesis of a Time History Based on the Sine-on-Random Prediction Methodology Defined in Mil-Std-810 Method 519 -- Michael Hale, Trideum Corporation

10:15 a.m. - 12:15 p.m.
Sensor Selection and Data Acquisition for Structural Measurements
Chair: Patrick Walter, PCB Piezotronics, Inc.
This session emphasizes how the measurement of meaningful structural response; whether in flight, field, or laboratory environments; depends on an integrated approach to instrumentation system design. Not only must the sensor selection be guided by the measurement objectives and operational environments, but the entire instrumentation system must concurrently be optimized to assure these objectives are met. Select presentations will reinforce this theme.

  • A Cube Sat Modal Survey -- Darren Fraser, Crystal Instruments
  • Uncertainties in Digital Data Acquisition – How good is my Measurement -- John Hiatt, Siemens PLM
  • A System Approach to Shock Accelerometer Design -- Patrick Walter, PCB Piezotronics, Inc.

1:15 - 3:15 p.m.
Providing Repeatable and Reproducible Environmental Test Results
Chair: George Coonley, Atlas Material Testing Technology
Modern testing demands conform to test requirements with the expectation that test results are repeatable and reproducible. Repeatable, as in, test-to-test and reproducible among instruments performing the same test (within or between test labs). In this session, issues and recommendations for reducing environmental test variability is reviewed and discussed. Topics include: Sources of test repeatable and reproducible variability; Environmental (temperature/humidity/air flow) repeatable and reproducible issues; Solar radiation repeatable and reproducible issues; Corrosion chamber repeatable and reproducible issues; and Equipment set-up and maintenance repeatable and reproducible issues.

  • On the Data Acquisition and Analysis of Li-ion Cells Aged Under Various Temperature Environments -- Sian-Syan Chyan, National Chung Shan Institute of Science & Technology
  • Characterizing the Global Temperature and Humidity Environmental Severity with Test Standards -- Dustin Aldridge, Raytheon Missile Systems
  • Blowing Rain, Sand and Dust Testing: Creating a more Repeatable and Reproducible Test Environment -- Matthew Lucas, US Army Redstone Test Center

3:30 - 5:30 p.m.
Product Development and Validation With Accelerated Testing (Deep Dive)
Chair: Dustin Aldridge, Raytheon Missile Systems
This brief workshop will discuss validation terms, test strategies supporting validation, current physics of failure models and their use in product development, reliability growth, validation, and damage analysis. Simple implementation examples will be provided.

Wednesday, May 10, 2017

8:00 - 10:00 a.m.
Understanding and Developing a Life Cycle Environmental Profile (LCEP)
Chair: Robert (Andy) Anderson, NTS
This panel discussion deals with the actual environments expected by hardware during its useful life and methodologies to translate the environments into testable requirements. LCEP is useful for both reliability and qualification requirement definition and to address the true risks of environmental loading on product life.

10:15 - 11:45 a.m.
Vibration Testing
Chair: David Sgro, FLIR, Inc.
Vibration testing can require unique setups, instrumentation variations, and well thought-out planning. This session will cover various aspects of vibration testing with a focus on new industry developments.

  • Utilizing Virtual Vibration Tests to Optimize Physical Shaker Tests -- Erik Ostergaard, HBM Prenscia
  • 6 Degree of Freedom Electrodynamic Vibration Test System -- Katsuhiko Nakamura, IMV Corporation
  • Fatigue Damage: Combine, Compare, and Quantify -- Andy Cogbill, Vibration Research

3:15 - 5:15 p.m.
Effective Fixturing for Electro-dynamic Vibration Systems

Chair: Milt Bos, Thermotron Industries

  • Fixture Design: Novel Drop Shock Fixture -- Alex Pless, Raytheon
  • Fixture validation – How to Determine the Quality of a Fixture -- Milt Bos, Thermotron Industries

Thursday, May 11, 2017

8:00 a.m. - 12:15 p.m.
MIMO Vibration Testing

Chair: Russ Ayres, Spectral Dynamics, Inc.

The use of multiple shakers to test large or complex structures is a growing testing technique. IEST Recommended Practice DTE-022, Multi-shaker Test and Control, provides a starting point for many potential multi-shaker testing organizations. When used in conjunction with the latest MIL-STD-810G, Change Notice 1, there is quite a bit of guidance available.

  • Square vs. Rectangular Control: Vibration testing of an aerodynamically excited structure -- Chris Roberts, Ministry of Defense
  • Minimum Drives Spectral Density Matrix for MIMO Random Vibration Control Tests -- Umberto Musella, Siemens Industry Software N.V.

1:15 - 3:15 p.m.
Vibration Controllers - New Developments and Technologies
Chair: Kevin McIntosh, Data Physics Corporation
In this session manufacturers of vibration control systems will present the latest developments in vibration control technology. Vibration controllers are critical instruments in performing dynamic testing in the vibration laboratory. From the very simple single axis transportation or commercial product testing to the most advanced multi-degree of freedom tests, vibration controllers are essential to successful product testing and qualification.
